Although I had registered for the Reston Bike Club (RCB) Century ride this year I’ve decided to volunteer my time to helping out with the amateur radio communications. This year I will be in SAG vehicle #4 so follow me around the course.
I’ve updated the weather section at w4mrw.org to include the following:
- Current and forecasted weather situation
- NOAA satellite images
- Latest Hazardous Weather Outlook text
- Weather Alerts for Fairfax County
After last week’s shooting at a movie theater in Aurora, Colo., the city of Houston has released a how-to video on surviving a shooter event.
The video was created with funds from the Homeland Security Department.
Entitled “Run, Hide, Fight,” the video depicts a fictional shooting incident at an office building.
“It may feel like just another day at the office, but occasionally life feels more like an action movie than reality,” says a narrator.
The City of Houston’s website offers these tips:
- Run if a safe path is available. Always try and escape or evacuate even if others insist on staying.
- Encourage others to leave with you but don’t let the indecision of others slow down your own effort to escape.
- Once you are out of the line of fire, try to prevent others from walking into the danger zone and call 9-1-1.
- If you can’t get out safely, find a place to hide.
- When hiding, turn out lights, remember to lock doors and silence your ringer and vibration mode on your cell phone.
- As a last resort, working together or alone, act with aggression, use improvised weapons and fight.
Houston’s Public Safety Office said it had started working on the video before the theater shooting, according to an ABC station in Houston.
One of the great features of FLDIGI is the ability to setup a station that can monitor Narrow Band Emergency Message System (NBEMS) messages and to then have those messages either pop-up in a FLMSG window or a browser window or both. This is useful if you are away from your station during an event .
There a number of steps to setup your station correctly and this HOWTO guide will step you through that process.
To begin with it is recommend that you download and install the latest FLDIGI, FLMSG and FLWRAP applications from http://www.w1hkj.com/download.html
If you are installing on a Windows Vista or Windows 7 machine it is recommended that you install to a folder where your logged in user has both read/write permissions. For example, installing to C:\NBEMS
Once you have FLDIGI, FLMSG and FLWRAP installed we need to configure FLDIGI to detect the different modes that may be transmitted and to then display the messages received.
1. To setup FLDIGI to detect messages sent using the Reed-Solomon ID you need to enable the RxID feature. When this is enabled and a message is sent with a Reed-Solomon ID FLDIGI will detect that message within the current passband and automatically center on that message, switch modes and start to decode the message. To send messages with the Reed-Solomon ID the TxID feature needs to be enabled. Recommend that you have both RxID and TxID enabled.
2. You may want to fine tune the settings for the receiving of the Reed-Solomon ID’s to do this select Configure | IDs from the FLDIGI menu.
3. If you want to search the entire passband for Reed-Solomon IDs check that option. When the option is unchecked FLDIGI will limit the search to +/- 200Hz of the current center frequency on the waterfall. Once you have made your changes make sure to click Save and then Close.
4. To select which modes will be detected click on the Receive modes button.
In the example above I am only interested in detecting MT63 and Olivia messages.
5. Now that you have FLDIGI setup to detect messages sent with the Reed-Solomon ID the next steps are to configure FLDIGI to extract messages that have been wrapped using FLWRAP or FLMSG and to pop open those messages in either FLMSG, your internet browser or both.
6. Select Configure | Misc from the FLDIGI menu. From the second row of tabs select NBEMS.
7. The first step is to locate the FLMSG executable file. Click Locate flmsg and navigate to the location where you installed FLMSG and select the flmsg.exe
8. Next step is to decide if you want the messages to open with FLMSG or in your default Internet browser. In the example above I have both, it’s personal preference.
9. Verify that you have the check box Enable under NBEMS data file interface checked.
10. Click Save then click Close.
Congratulations your station is now setup to detect messages (that you specified in Step 4) that are sent with a Reed-Solomon ID . If the message was sent as a wrapped message using either FLMSG or FLWRAP the message will pop up in either FLMSG or your Internet Browser or both.
UPDATE: SKYWARN is no longer active.
SKYWARN has been activated in watch mode on the 147.300+ repeater.
All SKYWARN spotters are requested to check their systems and back up systems at this time.
The National Weather Service has indicated that there is a threat for severe weather within the listening area of the 147.300+ Bluemont repeater.
